| Summary: | 博士 === 淡江大學 === 資訊工程學系博士班 === 96 === The multi-service supporting is the main requirement in multimedia wireless communication system. Internet has many services widely to use. Therefore, it is significant to integrate heterogeneous networks into a mobile All-IP network. Furthermore, bandwidth management is a very important theme for integrating a wireless communication system.
We refer the EVOLUTE (a project of Information Society Technologies, IST) that mingles Session Initiation Protocol (SIP) with Mobile IP (MIP) to support macro-mobility management and Cellular IP (CIP) to support micro-mobility. In this dissertation, we utilize Multicast-based Mobility (M&M) to assist CIP in micro-mobility management. Our aim is to provide a complete integration of heterogeneous networks, support a seamless handoff for micro-mobility management and decrease the handoff latency. The cooperation of M&M and CIP suits the macro-mobility management, proposed by EVOLUTE, to support real time and non-real time data flow in micro- mobility.
This dissertation also proposes a bandwidth management method, called Bandwidth Management and Disposition (BMD). The BMD computes the Reword Point (RP) to quantify the Mobile Host’s (MH) requests, and computes the Upgrade Rank (UR) or Downgrade Rank (DR) to quantify the upgraded or downgraded sequence of bandwidth, respectively.
Simulation results show that the proposed micro-mobility management schema achieves better performance. We also demonstrate that the method satisfies the demanding of multimedia services. The incremental rate of achieved request is 12.52% and rate of bandwidth usage is 2.4% when the system with BMD. We conclude that the proposed system facilitates further development of wireless communication networks.
